--- Most shipping APIs want a box: length, width, height, weight. People don't have that โ€” they have a thing on the table and a ZIP code to send it to. This server takes the thing. Describe **"a full-size acoustic guitar in its hard case"** and it estimates the packed carton, prices it live across three carriers, and hands back services you can actually buy โ€” with the checkout total and the carrier's own cost side by side, so you can always show a person both numbers. ## What you can ask your assistant - *"How much to ship a 12 lb box from 07922 to 90011?"* - *"What would it cost to send a full-size acoustic guitar in a hard case from New Jersey to Los Angeles?"* - *"Compare USPS, UPS and FedEx for a 5 lb box, Newark to Chicago โ€” which is cheapest and which is fastest?"* - *"Price a 24 ร— 18 ร— 12 in box at 22 lb going to 33101, then give me a link to buy the label."* - *"Where is my package? Tracking 9400111899561234567890."* - *"Did they pay for that label yet? Here is the session id you gave me."* - *"What has a 5 lb box to Denver cost over the last few months?"* - *"I have a pallet of ceramic tile going from Hoboken to Miami โ€” can you get me a quote?"* That last one is not a parcel, and the server says so rather than guessing: it returns a task handle, a person prices the freight, and the answer comes back when you poll it. ## Tools | Tool | What it does | |---|---| | **`get_parcel_quote`** | Live rates for one parcel from a US origin, domestic or to Canada, the UK, Germany or Australia, across USPS, UPS and FedEx, plus DHL Express to Germany and Australia. Plain-words description โ†’ estimated packed box; or pass exact dimensions and weight to skip the estimate. Returns up to five purchasable services with the checkout total (SMKlog fee inside), the carrier's counter price beside it where one is published, and the delivery window. | | **`create_checkout_link`** | Prices the shipment and returns a payment session: the amount, a handoff URL that opens the SMKlog checkout prefilled with this shipment, and a `session_id`. The human confirms the contents certification and the carrier-adjustment consent there and pays on Stripe. | | **`get_checkout_status`** | Where a payment session stands: `awaiting_checkout`, `checkout_started`, `paid`, `label_ready` (with the tracking number), `delivered` or `refunded`. Read from the order record, so it costs no carrier call and never carries names, addresses or emails. Sessions answer for 30 days. | | **`track_parcel`** | Delivery status, scan events and the carrier's estimated delivery date for a shipment whose label was bought on smklog.com. Not a universal tracker for arbitrary numbers. | | **`get_price_index`** | The monthly SMKlog parcel price index: six common boxes (1โ€“20 lb) from Newark, NJ to five US cities, repriced through the same live pipeline that prices real shipments. Reading it spends no quote allowance. | ## Things worth knowing before you wire it in **A quote is a real carrier call and costs real money to produce.** Call `get_parcel_quote` once per shipment, not once per variation you are curious about. The server is rate limited per client and will say so plainly rather than silently degrading. **Origin is the United States.** Domestic lanes and US-origin exports. A lane that starts somewhere else is out of scope, and the server will tell you instead of inventing a number. **Prices are checkout totals with the SMKlog fee inside.** The fee is itemized only on the checkout receipt; what comes back beside a rate is the carrier's own counter price for the same parcel, where one is published โ€” what the person would pay walking into the carrier's counter instead. The total is what they pay. **Oversized, palletized and multi-piece freight is priced by a person.** Declare the `io.modelcontextprotocol/tasks` extension and `get_parcel_quote` returns a task handle for those; poll it with `tasks/get`. **Nothing here buys a label on its own.** `create_checkout_link` produces a URL; a human completes the purchase, certifies the contents and consents to carrier adjustments. An agent cannot spend someone's money through this server. ## Connect ```json { "mcpServers": { "smklog": { "type": "http", "url": "https://quote-api.smklog.com/mcp" } } } ``` No key, no OAuth, no signup. Quoting, tracking and the price index are all open. ### Over stdio For a client that only launches local commands โ€” Claude Desktop, Cursor, an MCP inspector, a Docker-based runner โ€” this repository is a thin stdio bridge to the same endpoint. No dependencies, no build step, no keys: ```json { "mcpServers": { "smklog": { "command": "npx", "args": ["-y", "github:smklog/parcel-shipping-rates-mcp"] } } } ``` Or with Docker: ```sh docker build -t smklog-parcel-shipping-rates-mcp https://github.com/smklog/parcel-shipping-rates-mcp.git docker run -i --rm smklog-parcel-shipping-rates-mcp ``` The bridge forwards every JSON-RPC message to `https://quote-api.smklog.com/mcp` and writes the answer back, one JSON object per line. It also mirrors the 2026-07-28 routing envelope into HTTP headers (`MCP-Protocol-Version`, `Mcp-Method`, `Mcp-Name`) and, on the legacy path, sends the version `initialize` negotiated, so both protocol eras work through it. If the endpoint cannot be reached it still answers `initialize` and `tools/list` from the snapshot shipped here (`initialize.json`, `tools.json`), so you can see what is offered; tool calls need the network. `npm test` drives it end to end.
